Title: PROCESS OF PRODUCING TACTILE DOTS, TACTILE DOT GROUPS, AND TACTILE IDENTIFIER MARKS
Abstract:
Techniques are described for the production of tactile dots, tactile dot groups, and tactile identifier marks on substrates that are tactilely recognizable by visually impaired individuals. Each tactile dot can be formed individually in the substrate, for example by separately embossing each tactile dot using a single punch and die pair. By using a single punch and die pair, the size, complexity and cost of the tactile dot embossing mechanism can be reduced, and the spacing between the tactile dots can be varied.
